Hardeners Formaldehyde scavengers Resin extenders

Fire retardants Additives for paper impregnation Recycling agents

CHIMAR Hardeners

Resin hardeners or curing agents:

they accelerate the resin polymerisationHardener technologies for all types of resins and wood panels

Hardeners in either solid or liquid formCan be used either alone or in combination with conventional hardeners

CHIMAR Hardeners: Advantages

Their application helps to reduce the press cycle thus

increasing the productivity by up to 20%

The board properties are improved enabling reduction of the resin level and thus reduction of the production cost

In the case of MUF resins, CHIMAR special hardeners helped to improve the panels water resistance thus

allowing the reduction of melamine content and

therefore cost savings

CHIMAR Formaldehyde Scavengers

CHIMAR scavengers are used to reduce the

formaldehyde emissions during panel production as well as the emissions of finished panels

Scavenger technologies for amino resin types

(UF, UMF, MUF)

Scavengers are tailor-made to satisfy the plant

requirements and operating parameters

(e.g feedstocks, final product requirements)

First scavengers were commercially introduced on a

Formaldehyde Scavengers Action

Synergistic action of CHIMAR amino resins and

scavengers provides panels with desirable properties and formaldehyde emission as low as required

Scavenger grades for achieving E1, half E1 (EPF-S or IOS-MAT-0003), E0 and even SE0 (F*** and F****, JIS

A 1460)

Scavengers reduce formaldehyde emission

permanently

CHIMAR Resin Extenders

CHIMAR extenders are used to substitute part of the resin applied in panel production at no sacrifice of the panel properties, thus offering cost savings

Extender technologies for amino and phenolic resin types

Extenders are tailor-made to satisfy the plant

requirements and operating parameters (e.g

feedstocks, final product requirements)

CHIMAR Extenders: Advantages

Their application provides up to 10% savings on the binder cost

When applied, the extenders induce no changes in board production process, therefore no additional

CHIMAR Fire Retardants

CHIMAR provides technologies for fire retardant compositions effective in enhancing the panel fire resistance at desirable levels

Advantages offered:

™Non-corrosive and halogen-free products

™High retention of properties - IB, MOR, swelling

™No deterioration of the properties with time

™No increase in formaldehyde emission, possible

CHIMAR PYRO-S series

Patent protected WO 02/102926

Application in MDF

In liquid form, readily added in the blowline through

a nozzle

Dosing 10-15% w/w based on dry fibres (depending

on the plant operating parameters and the desired final product specifications)

Can only be mixed with the glue in a static mixer

CHIMAR PYRO-SM series

Application in PB

In solid form

Can be added in all board layers

It is preferably added on the chips before the

blender

Dosing 15-20% w/w based on dry chips (depending

on the plant operating parameters and the desired final product specifications)

Additives for Paper Impregnation

CHIMAR provides technologies for the production of additives used in paper impregnation:

™ Wetting agents

™ Release agents

™ Hardeners

Hardeners for Paper Impregnation

Their application allows the reduction of the reduction of the

hardener level and thus reduction of the production cost

They are easily applicable in conventional

impregnation lines

They provide impregnated paper and laminated

boards with equal or even improved quality as

CHIMAR Recycling Process

CHIMAR Recycling Agents

As part of this recycling process, a chemical

composition (recycling agent) prepared according toCHIMAR technology is injected in the digester to promote fibre recycling

Cost savings may vary from plant to plant,

depending on fuel self-sufficiency and waste panel availability
